Abstract

The present invention relates to the technical field of radars and particularly relates to a multi-target tracking method and a tracking system for the track management of a marine navigation radar. The method comprises the steps of collecting a plurality of groups of radar data from a radar; according to the tracking duration and the tracking state, selecting suitable wave-gate parameters; preliminarily giving the tracking state of a tracked target in the current frame according to the corresponding relationship between trace points and a track during data interconnection, and simultaneously calculating the physical parameters of the tracked target; according to a track cancellation criterion, judging whether the tracked target is lost or not based on the previous tracking state of the tracked target; calculating the tracking quality and the track number of the tracked target; updating the state and the related parameters of the tracked target in the current frame, and updating the track file of the tracked target; according to the tracking quality and the track number, confirming whether the track of the tracked target is outputted or not, and outputting the track.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a multi-tracking target tracking method and system for ship navigation radar track management. Background technique [0002] In recent years, with the complex and changeable application environment, radars are required to have multi-tracking target tracking capabilities, and can simultaneously realize multi-tracking target tracking; the basic concept of multi-tracking target tracking was published by Wax in 1955 in Applied Physics Journal In 1964, Steer published a paper entitled "The Optimal Data Association Problem in Surveillance Theory" on IEEE, which became the forerunner of multi-tracking target tracking, but Kalman filtering was not yet widely used at that time. , Steer used a track bifurcation method to solve the data association problem; in the early 1970s, in the presence of false alarms, the Kalman filter method (Kalman) was used to systematically track and track multipl...
